A Plastic Tide: Combatting the Scourge of Microplastics in Our Seas and Rivers
A Plastic Tide: Combatting the Scourge of Microplastics in Our Seas and Rivers
It was hailed as one of the finest wildlife television series ever made and at the end of the final episode of BBC's Blue Planet 2 last December, David Attenborough issued a plea: "The future of humanity - and all life - now depends on us."Earlier, viewers had watched aghast as the scale of the plastic pollution in the world's oceans was laid bare. It depicted albatross parents unwittingly feeding their chicks plastic and mother dolphins potentially exposing their newborn calves to pollutants through their contaminated milk. For many, it was an eye-opener about the harm that plastics - and our dependence on them - have caused to marine life all over the world. But it was no surprise to Karin Dubsky of Trinity College Dublin. The founder of Coastwatch Europe, the German-born campaigner is one of the country's foremost experts on how this island nation has been relentlessly polluting our seas and rivers with plastic. "Thirty years ago," she says, "the huge concern was oil spills, but now it's plastic and it's having a hugely detrimental effect. We've seen increased mortality in many species due to ingestion and entanglement."While there's some commendable volunteer work being conducted to clean up plastic litter in several coastal areas throughout the country, Dubsky insists it's only scratching the surface. "It's impossible to underestimate the impact that microplastics are having on marine life," she says. "It's causing havoc."Microplastics are defined as being less than 5mm in size and there are countless trillion of them in the world's waters. Together with 'microbeads' - a form of plastic used in several industries, including cosmetics where they're used in exfoliating products - they are ingested by seafood that we readily consume. That's a huge cause for concern, Dubsky insists. "There was a study by students from NUI Galway which looked at muscles caught on the west coast, and while some had some plastic contamination, others were very heavily contaminated. And we're eating them."The same study also uncovered evidence that Dublin Bay prawns (Norway lobster) caught on the west coast also were contaminated by plastic. Plastic is not biodegradable and the smaller it gets, the greater the trouble it causes to marine life - everything from a tiny plankton to an enormous whale. But larger plastics can be hazardous, too. Last year, there was shock when a photo emerged of naturalists in Norway displaying the 30 large plastic bags that had been found in the stomach of a beached whale. Dubsky was one of the primary campaigners for the introduction of the plastic bag levy and she says it's had a noticeable impact on our coastline. "When we conduct surveys now, there's only a fraction of the plastic bags that we used to see."Last year, Coastwatch found two plastic bags per site surveyed, rather than 18 bags in the same areas in 2004, two years after the levy was introduced. "It's certainly helped change people's behaviour, and it's had a direct improvement when it comes to our coastlines. We need to introduce more incentives."One of the most significant of the bigger plastic pollutants on Irish coasts are drink bottles and their lids. "If we had a deposit-return system for bottles, it would transform the situation," she says. "In Germany, where such a system is in place, you almost never see plastic bottles littering their shores and towns."And the problem is a significant one. In a Coastwatch survey last autumn, an average of 18 plastic drinks bottles per 500m of shore were found, and while it is the lowest number recorded since the early 1990s here, it is still indicative of a culture where many of us still seem happy to litter the natural environment. "We have to put pressure on retailers and manufactures not to use plastics. There is a direct link between the needless use of plastic to wrap fruit and vegetables in our supermarkets and the amount of plastic that's polluting our waters," Dubsky says. But she's keen to stress it's not just the consumer who's to blame. The commercial fishing industry has played a big part in plastic pollution thanks to its use of 'dollies' - plastic coatings for the bottom of dragnets to preserve their longevity - and traditional non-plastic lobster and crab traps have been widely replaced with plastic ones and some of them wind up on the sea floor. "You need only go out to Howth (Co Dublin) to see all these plastic traps lined up at the pier."Quite how much plastic is in the world's oceans remains a mystery, although there were suggestions this week from international scientists that plastic in the oceans may cumulatively equate to the total landmass of Mexico. "And all this has happened in the space of about 50 years," Karin Dubsky says. "It's only in that time that plastics have become commonplace. But we have the knowledge now of the harm they are causing and it is up to each and every one of us to take action and reduce or plastics usage."Indo Review
LED Lighting Will Completely Solve the Price Problem to Popularize the Application
LED Lighting Will Completely Solve the Price Problem to Popularize the Application
LED lighting, which has been promoted for many years, has been used in places requiring 24-hour lighting such as medical treatment and hotels, as well as areas requiring long-time lighting such as street lamps due to its high cost. Other areas have not been able to enter on a large scale due to price reasons. However, this year and next may be a turning point."The price of LED lighting decreased very fast in 2012, which makes LED lighting rapidly enter various application fields." Wang Yongbin, marketing director of lighting products in Greater China of NXP semiconductor (NXP), analyzed this magazine on the occasion of the 2012 Hong Kong autumn lighting exhibition, "In addition, we found a new trend, that is, non dimming LED lighting products are very popular among Asians, including developed countries such as Japan and South Korea, which may be related to their use habits. Europeans and Americans prefer dimming lighting." This is good news for the LED industry, because at present, the price of non dimming IC is about half cheaper than that of dimmable IC, and IC is still the most important part of the cost of the whole LED lamps. Wang Yongbin then added: "another trend we found is that after continuing the LED ball gun and tube series, LED lamps will begin to become the mainstream demand in the next year." Therefore, in the next year, NXP and other LED semiconductor solution providers will focus on the non dimming and high-power lamp market, because the growth potential in Asia is huge.In addition to the above trends, Wang Yongbin also revealed that at present, lighting manufacturers have high requirements for power factors, because many countries, including China, especially require the FP of some lighting to be greater than 0.9, and will subsidize up to standard products. "For example, in the bidding of China's energy-saving and people-friendly projects, two points will be added for products with FP greater than 0.9, and the Chinese government will give supplementary posts. In addition, it is also required in the European energy star that when the power is greater than 25W, the FP must be greater than 0.9." He pointed out that in the schemes of some IC manufacturers, the realization of high-power factors needs to be controlled from the outside, which will increase the cost, while NXP can be realized from within the chip, which is not only convenient for design, but also reduces the cost. "For example, the ssl2109a controller can realize FP greater than 0.9, less peripherals and simple and convenient design due to the use of special circuits." he cited an example.It is also aimed at another product series ssl21081 (a) / 83 (a) of non dimming integrated high-voltage MOSFET, with high integration, less peripheral components, only 14 required, and lower overall cost. Due to the integration of MOSFET, the efficiency can reach more than 95%. However, at present, the FP of this scheme can only be greater than 0.7. "Ssl21081 (a) / 83 (a) It can achieve 5% current precision control and 95% efficiency output, complete protection functions and built-in flexible and reliable features, ensuring the lowest system component cost. It is welcomed by users in Asia and will be the main product this year and next. " He explained that not all IC companies can integrate the high-voltage MOSFET into the controller. NXP can achieve good heat dissipation due to the high-voltage SOI insulation process, so as to integrate the high-voltage MOSFET to achieve efficient lighting. For some companies that integrate 750V MOSFET, while NXP only integrates 600V MOSFET, Wang Yongbin explained that at present and in the near future, integrating 600vmosfet is enough and more The result is waste and increased costs.For the high-power LED lamp market that will become the mainstream in the next year, NXP launched ssl4120 in Hong Kong this time, which is an integrated success rate factor correction (PFC) GreenChip? Half bridge resonant controller can support high-power LED applications up to 400W. At present, it has been mass produced and samples will be available soon. Ssl420 fully supports commercial power applications and supports efficient start-up directly from the rectified general commercial power voltage range of 90 to 305 volts. In addition, it also supports low total harmonic distortion (THD) of less than 10% and high power factor of higher than 0.97 (PF) and 380 kHz typical PFC frequencies meet and exceed the traditional requirements of high-power LED lighting applications. Ssl4120 can be widely used in high-power LED applications, such as office lighting, shopping mall lighting, high and low shed lighting, parking lot lighting, square lighting and street lighting.For the confrontation between single-stage and two-stage LED driver architectures in the current market, Wang Yongbin said that NXP is the defender of single-stage architecture. The main reasons are as follows: first, NXP has long-term accumulation and advantages in single-stage; second, single-stage controller can integrate high-voltage MOSFET; third, single-stage is easy to use and easy to design, and customers can develop successfully in only two weeks; fourth, single-stage is successful at present This advantage, two-level BOM is about 10-15% more expensive than single-level BOM.Finally, when it comes to the trend of some lamp manufacturers to do vertical integration, R & D and drive IC / components, Wang Yongbin believes that this is only a temporary phenomenon and will not become the mainstream. "It is still difficult for companies making lamps to do the electronic part. In the future, they will still specialize in the division of labor, and the driving part will be independent." he personally believes.
