AbstractHigh emission of tire rubber particles to the surrounding environment is an inevitable consequence of the current habits of transportation. Although most of the emissions stay within a close range of the sources, it has been proven that the smallest particles can be transported to remote locations through the atmosphere, including inland water bodies. It has been estimated that a relevant portion of the global emissions of tire rubber particles reach surface waters, but effects on aquatic life in the receiving water bodies are not completely understood. In the present study, we used the freshwater sediment dwellers Lumbriculus variegatus and Chironomus riparius to examine the toxicity of tire rubber particles at environmentally relevant concentrations, using different types of sediment and two particle sizes of tire rubber. Overall, the experiments were unable to discern any effects on the growth, survival or reproduction of the two animals tested. Significant differences were found among the animals dwelling on different sediments, but the effects were not attributable to the presence of tire rubber particles. This study provides important information regarding the lack of effect of tire rubber particles in laboratory experiments with model sediment dwellers and opens more questions about the potential effects of tire rubber particles in the real environment with longer durations and varying environmental factors. The influence of other factors such as the leaching of additives in the overall toxicity of tire rubber particles should be also considered.

AbstractAgricultural production is strongly affected by and a major contributor to climate change. Agriculture and land-use change account for a quarter of total global emissions of greenhouse gases (GHG). Agriculture receives around US$600 billion per year worldwide in government support. No rigorous quantification of the impact of this support on GHG emissions has been available. This article helps fill the void. Here, we find that, while over the years the government support has incentivized the development of high-emission farming systems, at present, the support only has a small impact in terms of inducing additional global GHG emissions from agricultural production; partly because support is not systematically biased towards high-emission products, and partly because support generated by trade protection reduces demand for some high-emission products by raising their consumer prices. Substantially reducing GHG emissions from agriculture while safeguarding food security requires a more comprehensive revamping of existing support to agriculture and food consumption.

Aquatic Life

On account of industrialization and increasing population, the water bodies get polluted by means of degradable and non-degradable substances. In 21st century, it is necessary to maintain a healthy environment especially water bodies for the survival of not the aquatic animals but also for healthy human life. Recent advances suggest that the issues related to water quality could be resolved by using nanoparticles and nano-filtration membrane methods from the development of nanotechnology. In this research, attempt to remove heavy metals from Chithrapuzha River water at Cochin bar mouth (S1) and Fact barge jetty (S2) using Fe2O3 prepared via green synthesis using Egg albumin and Aloe vera. Our results provoke that, the synthesis of Fe2O3 nanoparticle is cost-effective and eco-friendly and also good in nano-regime. Results of filtration studies showed that Fe2O3 nanoparticles remove heavy metals from Chithrapuzha River water and also increases the DO content which helps the survival of aquatic life.
