Safety risk study on road transportation of hazardous chemicals is a reliable basis for the government to formulate transportation planning and preparing emergent schemes, but also is an important reference for safety risk managers to carry out dangerous chemicals safety risk managers. Based on the analysis of the transport safety risk of dangerous chemicals at home and abroad, this paper studi...

Many prey species detect chemical cues from predators and modify their behaviours in ways that reduce their risk of predation. Theory predicts that prey should modify their anti-predator responses according to the degree of threat posed by the predator. That is, prey should show the strongest responses to chemicals of highly dangerous prey, but should ignore or respond weakly to chemicals from ...

The European Union has published a list of dangerous chemicals, along with classification and labeling; in 1997 the list was adapted to the requirements of Polish regulations and has been continuously updated since then. We have decided to adopt data on dangerous chemicals classification in the list referring to their dermal absorption to assess whether the skin notation is required in the maxi...

INTRODUCTION In a previous paper it was shown that the practice of storing time-sensitive chemicals for extended periods is dangerous. As one reviews the literature, one observes more and more cases of time-sensitive chemicals being stored for prolonged periods. Sometimes these chemicals are also improperly stored. Questions that come up include how time-sensitive chemicals are identified, what...

Stability of water ecosystems is often disturbed by dangerous chemicals – products of human activities having negative economical and environmental impact. Oil spills are typical examples of these dangerous chemicals. They are eliminated with different strategies, e. g. self-cleaning of water surface, usage of booms, collectors of oil spills or autonomous robots. This paper investigates the app...
