Shopping bags have posed significant environmental burdens. The integrated model of theory planned behavior (TPB) and norm activation (NAM) was proposed to predict individuals' choice shopping bags. Data from a cross-sectional study with total 536 respondents in Vietnam used test the models hypotheses. Results linear regressions indicated that socioeconomic factors possibly were confounding for...
Despite the large and growing literature on microplastics in the ocean, little information exists on microplastics in freshwater systems. This study is the first to evaluate the abundance, distribution, and composition of pelagic microplastic pollution in a large, remote, mountain lake. We quantified pelagic microplastics and shoreline anthropogenic debris in Lake Hovsgol, Mongolia. With an ave...
Floating persistent debris, primarilymade fromplastic, disperses long distances from source areas and accumulates in oceanic gyres. However, biofouling can increase the density of debris items to the point where they sink. Buoyancy is related to item volume, whereas fouling is related to surface area, so small items (which have high surface area to volume ratios) should start to sink sooner tha...
Plastic litter is found everywhere. Walk onto any beach around the world and you will almost certainly find plastic. The harm that large plastic can cause to marine animals well-known; for example, may have seen sad pictures of turtles eating bags or seals tangled in discarded fishing nets. However, scientists are also concerned about microscopic-sized we do not normally see, problems these tin...
The discovery of a letter intentionally filled with dried Bacillus anthracis spores in the office of a United States senator prompted the collection and quarantine of all mail in congressional buildings. This mail was subsequently searched for additional intentionally contaminated letters. A microbiological sampling strategy was used to locate heavy contamination within the 642 separate plastic...
