《中国证券报》9月18日报道，近日环境保护部会同国家质检总局发布了《轻型汽车污染物排放限值及测量方法（中国第五阶段）》（以下简称国五标准）等两项国家大气污染物排放标准。国五标准实施方案进一步突出了“车、油适配”原则：轻型汽车自标准发布之日起可依据新标准进行型式核准；鼓励具备燃油供应条件的地方依法提前实施新标准。实施国五标准将大幅削减新车排放量，预计实施5年可减排9万吨氮氧化物、2万吨颗粒物，随着新车逐步上市，其环保效益将随着实施时间延长而逐年加大。

Activated carbon is a form of carbon with exceptionally high surface area and micro porosity for adsorption and chemical reactions. In order to manufacture activated carbon, commonly available materials such as coal, wood, or coconut shells are processed in the presence of heat and gas. The property of activated carbon to adsorb different substances is utilized in a variety of ways. The major application of activated carbon is in the Water Purification and Gas Treatment industries. Other applications of activated carbon include metal extraction, sewage treatment, gas filtration, pharmaceutical applications, food and beverage processing, and controlling emission from automobiles.

The Food and Agriculture Organization of the United Nations defines biopesticide as “a compound that kills organisms by virtue of specific biological effects rather than as a broader chemical poison." Biopesticides are living organisms that are used to destroy agricultural pests. As against chemical pesticides, whose residues have a tendency to bioaccumulate (accumulate in the bodies of living organisms and the food chain) and cause hazards to flora and fauna, biopesticides are beneficial to the ecological chain and the environment. Their benefits are mainly due to the following two reasons:The Global Biopesticides market was valued at US$1.47 billion in 2012. In 2012, North America contributed the major share to the Global Biopesticides market, and it was followed by Europe. The market in Europe is expected to be the fastest growing market for biopesticides during the period 2012-2016 because of its stringent regulations pertaining to human health and environmental safety. The Biopesticides market is expected to grow at a CAGR of 15.87 percent during the forecast period.
