Pesticides and Urban Contaminants
ثبت نشده
چکیده
The population of the southeast United States has experienced the highest growth rate in the nation in recent decades. Florida, in particular, has seen a dramatic population increase since the late 1970s, which has led to increased urbanization and more intense utilization of arable land for agriculture. One consequence of increased agriculture and population growth in South Florida is the potential for toxic effects in estuarine and marine areas caused by pesticides and contaminants associated with urbanization, such as PAHs, PCBs, and heavy metals.

Review of risk from potential emerging contaminants in UK groundwater.
This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the UK. EGCs are compounds being found in groundwater that were previously not detectable or known to be significant and can come from agricultural, urban and rural point sources. EGCs include nanomaterials, pesticides, pharmaceuticals, industrial compounds, personal ...
متن کاملFingerprinting groundwater pollution in catchments with contrasting contaminant sources using microorganic compounds.
Evaluating the occurrence of microorganics helps to understand sources and processes which may be controlling the transport and fate of emerging contaminants (ECs). A study was carried out at the contrasting instrumented environmental observatory sites at Oxford, on the peri-urban floodplain gravel aquifer of the River Thames and Boxford, in the rural valley of the River Lambourn on the chalk a...
متن کاملAcetylcholinesterase activity in grass shrimp and aqueous pesticide levels from South Florida drainage canals.
Freshwater drainage canals in South Florida are utilized to manage water in agricultural, urban, and water conservation areas and, as a result, collect urban and agricultural storm runoff that is discharged into the Atlantic Ocean and Gulf of Mexico. Pesticides in this runoff may be toxic to the biota inhabiting these waters. This study evaluated the effects of contaminants in South Florida can...
متن کاملChlorinated organic contaminants in breast milk of New Zealand women.
Breast milk samples from 38 women in New Zealand were analyzed for organochlorine pesticides, polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) as part of a World Health Organization collaborative study of breast-milk contaminants. The women were recruited from two urban areas (Auckland and Christchurch) and two rural areas (N...
متن کاملSurveillance for previously unmonitored organic contaminants in the San Francisco Estuary.
The San Francisco Estuary Regional Monitoring Program initiated surveillance monitoring to identify previously unmonitored synthetic organic contaminants in the San Francisco Estuary. Organic extracts of water samples were analyzed using gas chromatography-mass spectrometry in full scan mode. The major contaminant classes identified in the samples were fire retardants, pesticides, personal care...
