TL;DR: Information available recently shows that nitrites and nitrates are both oxidation products and ready sources of nitric oxide, that NO* reacts rapidly with superoxide to form highly reactive peroxynitrite (ONOO-), and that vitamin E may mediate the generation and availability of superoxide and NO*.

TL;DR: In this paper, the authors defined environmental and ecological impact assessment examples of environmental assessments. But they focused on road ecology and traffic biology of roads and roadside verges habitat fragmentation, barriers and corridors physical and chemical effects of road and traffic road kills.
Abstract: Roads and traffic scoping the ecology of roads and traffic biology of roads and roadside verges habitat fragmentation, barriers and corridors physical and chemical effects of roads and traffic road kills - animal mortality on roads reducing adverse effects the ecology of roads in future. Appendices: definitions environmental and ecological impact assessments examples of environmental assessments.

TL;DR: Infections such as that caused by type 29 can be eliminated, not by the massive use of antibiotics but by improvement in conditions of animal husbandry and reduction in the opportunities for the initiation and spread of the disease.
Abstract: A rise in Salmonella typhimurium infection was observed in calves in Britain during 1964–6, follwing the adoption of the intensive farming method. A single phage type of S. typhimurium, type 29, was incriminated as the major pathogen. Attempts to treat and control the disease with a range of antibiotics were ineffective, but resulted in the acquisition of transferable multiple drug resistance by type 29. The transmission of drug-resistant type 29, directly or indirectly, from bovines to man resulted in many human infections. Transferable drug resistance reaching man from enterobacteria of animal origin may ultimately enter specifically human pathogens. Infections such as that caused by type 29 can be eliminated, not by the massive use of antibiotics but by improvement in conditions of animal husbandry and reduction in the opportunities for the initiation and spread of the disease. A reappraisal is needed of the methods of using antibiotics to determine how these methods can be improved, in order to conserve the long-term efficacy of the antibiotics.

TL;DR: With 2266 road-killed animals representing 97 species, the results of a study on a motorway section emphasized that traffic considerably affected vertebrate populations, and animal mortality exponentially increased with traffic volume.
Abstract: Although motorways could affect wildlife species, only few studies have been documented on their effects on mortality and isolation. With 2266 road-killed animals representing 97 species, the results of a study on a motorway section emphasized that traffic considerably affected vertebrate populations (14.5 animals day−1100 km−1). Road-killed animals were mainly mammals (43.2%), with predators also suffering critical impacts (21.7% vertebrates). Rare or endangered species such as the Midwife toad, the Blue throat, the little Horseshoe bat, or the European otter were among the victims. Animal mortality exponentially increased with traffic volume. Mortality reached almost 100% of migrants when no passage existed, and this barrier effect was only reduced when underground passages crossed the road restraining the mortality to 31% of migrants in Field mice and 23% in Common toads, while mortality always exceeded 74% in a road section with fauna ducts. It is reasonable to conclude that traffic severely ...
