European subsidies to enhance farmland wildlife may not be working.
The effectiveness of schemes that seek to promote biodiversity by paying farmers to cut back on intensive agriculture could be called into question by some research findings from Holland.

Air pollution used to be something you could see and smell. But as air quality standards have tightened, the air over most industrial sites, airports and cities has gradually cleared. Nevertheless, invisible toxic agents such as ethyl benzene, butadiene and styrene continue to pose risks to public health. With a view to detecting and quantifying these agents, Siemens Environmental Systems Limited in Poole, England has introduced UV Falcon. The system consists of a transmitter that projects a UV (ult
