Surface water monitoring for pesticides in agricultural areas of California is one of the California Department of Pesticide Regulation’s (CDPR’s) key environmental monitoring activities. The Salinas, Santa Maria and Imperial valleys have previously been designated as high priority areas for long-term surface water monitoring due to high pesticide use. This 2013 study is a continuation of the agricultural monitoring project.
Pesticide occurrence was determined in two suburban surface waters in eastern Massachusetts, USA during 2009 and 2010. Out of 118 collected samples, 45 samples showed detections of one or more target pesticides. Among the herbicides, 2,4-D was the most frequently detected and imidacloprid was the most frequently detected insecticide. Regulatory phaseout of chlorpyrifos and diazinon from residential use by 2004 was reflected in the results by the absence of chlorpyrifos detections and lower detection frequencies of diazinon.
UK BUTTERFLIES suffered their fourth worst year on record in 2016 with the majority of species experiencing a decline in numbers, a study has revealed. The annual UK Butterfly Monitoring Scheme, led by Butterfly Conservation, the Centre for Ecology and Hydrology, British Trust for Ornithology and Joint Nature Conservation Committee, revealed that some 40 of the 57 species studied recorded a decline compared with 2015.
Among a growing list of species in need of federal protections, the U.S. Fish and Wildlife Service has placed the Knowlton’s cactus and Uncompahgre fritillary butterfly on the endangered species list. According to Fish and Wildlife, an endangered listing is any species in danger of extinction through all or a significant portion of its range, whereas a threatened listing is any species that is likely to become endangered within the foreseeable future.
Honeybees -- employed to pollinate crops during the blooming season -- encounter danger due to lingering and wandering pesticides, according to a new Cornell University study that analyzed the bee's own food. Researchers used 120 pristine honeybee colonies that were placed near 30 apple orchards around New York state. After allowing the bees to forage for several days during the apple flowering period, the scientists examined each hive's "beebread" -- the bees' food stores made from gathered pollen -- to search for traces of pesticides.
The population of the northern long-eared bat (Myotis septentrionalis), a species once common in Missouri caves, dropped from 2,684 in 2015 to only seven last winter, which could lead to a "domino effect" on the food chain and cave ecosystems, conservation officials said. The Missouri Department of Conservation surveyed more than 300 caves and mines in the winter and found the alarming results when compared with surveys of 375 caves and mines in 2015, The Columbia Missourian reported (http://bit.ly/2p7bypK ).

A 15-mile stretch of the River Irwell has been poisoned after a suspected pollution incident. Conservation experts say all invertebrates along the waterway from Rossendale to Radcliffe, via Bury, have been 'wiped out', possibly by the dumping of a harmful pesticide. The vast majority of the bugs have also been wiped out from Radcliffe to Manchester city centre. An investigation has been launched by the Environment Agency after the incident was reported to the watchdog by the Mersey Basin Rivers Trust, which monitors the Irwell.
In 2010, my life changed when Dr Henk Tennekes and I traded books. His was: The systemic insecticides: a disaster in the making and ours was: The Year of the Bumblebee: Observations in a small Nature Reserve. Dr Henk Tennekes, an independent toxicologist based in the Netherlands, was the first researcher to recognise the extreme toxicity of low levels of systemic neonicotinoid insecticides that have become widespread in the environment.
Fewer birds appear to live in Vermont today than 25 years ago, according to recent research by the Vermont Center for Ecostudies. The most dramatic declines in bird populations were seen among those that live off flying insects, scientists say. Known as aerial insectivores, this diverse group of birds has declined 45 percent in Vermont, according to the study.
Regional Environment Awareness Cameron Highlands (REACH) president Ramakrishnan Ramasamy said most rivers in the highland, known for its tourism and agriculture, are heavily polluted. He said data from the Department of Environment (DoE) and the Drainage and Irrigation Department (DID) showed that only about 10 per cent of 123 rivers were in Class I and Class II, while the remainder were in Class III and Class IV. He also said three rivers had been declared biologically dead, and came under Class V of the classification.
