A new procedure to accurately define Nitrate Vulnerable Zones

The Nitrates Directive of the European Union (91/676/EEC) aims to reduce and prevent water pollution caused by nitrates from agricultural sources. It establishes that water resources should be considered polluted when nitrate concentration exceeds 50 mg L-1.

Trace gas emissions from husbandry by combining satellite airborne and surface observations

Animal husbandry produces the potent greenhouse gas, methane, which traps heat in the atmosphere (like carbon dioxide). This industry also produces ammonia, which leads to particle (smog) formation that’s dangerous when breathed and affects sunlight and thus

The destruction of endocrine disruptors in wastewater

In Canada, endocrine disruptors are a very topical issue in wastewater effluent quality. We define endocrine disruptors as chemicals that can interfere with the endocrine or hormone systems in wildlife and humans. Results can vary from different

Reflectance spectra of high-density polyethylene

There is growing global concern over the plastics pollution of our oceans and the many unanswered questions about its sources, sinks, pathways and impacts. Remote sensing (RS), the science of obtaining information about objects or areas from

How the seasnake lost its bands

Across Europe, the Industrial Revolution of the early 1800s blackened the trees with soot. That shift in color exerted strong evolutionary pressure on many species of insects that were camouflaged against natural tree-trunks but very obvious (to

Water pollution by anthropogenic sources such as industrial effluents, mining activities, use of fertilizers and pesticides, dumping grounds is increasing in alarming rate. Picric acid (2,4,6-trinitrophenol, TNP) is highly explosive molecule used in armour piercing shells, bombs,

The influence of pollution on bone premature aging: the case of the fishbone

Bone is one of the most sophisticated biological structures developed by nature, its major constituent is a calcium phosphate mineral that is similar, in composition and structure, to minerals within the apatite group which are naturally formed

Air pollution forecasting is required for citizens’ protection in urban environments

Air pollution is one of the most harmful factors posing threat to human health, worldwide. Of particular concern in urban environments are particulate matter (PM), especially fine (PM2.5) and ultrafine (PM1) fractions, ground-level ozone (O3), and nitrogen
