Pollution indices as useful tools for the comprehensive evaluation of the degree of soil contamination–A review

Environmental Geochemistry and Health, Год журнала: 2018, Номер 40(6), С. 2395 - 2420

Опубликована: Апрель 5, 2018

The paper provides a complex, critical assessment of heavy metal soil pollution using different indices. Pollution indices are widely considered useful tool for the comprehensive evaluation degree contamination. Moreover, they can have great importance in quality and prediction future ecosystem sustainability, especially case farmlands. Eighteen previously described by several authors (Igeo, PI, EF, Cf, PIsum, PINemerow, PLI, PIave, PIVector, PIN, MEC, CSI, MERMQ, Cdeg, RI, mCd ExF) as well newly published Biogeochemical Index (BGI) were compared. content, determined other authors, most investigated metals (Cd, Pb Zn) farmland, forest urban soils was used database calculation all presented indices, this shows, based on statistical methods, similarities differences between them. initially divided into two groups: individual complex. In order to achieve more precise classification, our study attempted further split their purpose method calculation. strengths weaknesses each index assessed; addition, choice is presented, best interpret (farmland, urban). This review also contains an various geochemical backgrounds (GBs) assessments. propose assess quality, application local reference GB.

In the last two decades, pressure from various stakeholders has forced many companies to establish environmental and social improvements both in their company supply chains. The growing number of journal publications conference proceedings confirms this change also academia. aim paper is analyse review scientific literature on sustainable supplier management (SSM) with a focus formal models supporting decision-making selection, monitoring development. For purpose, framework SSM proposed comprehensive content analysis including criteria carried out. Beyond this, total 143 peer-reviewed between 1997 2014 have been analysed identify established overlooked research fields. Major findings are rapidly interest topic academia recent years, predominance Analytic Hierarchy Process, Network Process fuzzy-based approaches, final evaluation selection process step rare investigation quantitative metrics. This may be useful for practitioners scientists as it outlines major characteristics field, which can serve basis further research.

Botanical insecticide as simple extractives for pest control

Cogent Biology, Год журнала: 2017, Номер 3(1), С. 1404274 - 1404274

Опубликована: Янв. 1, 2017

One of the most important global problems is protecting crops from insects. For control insects, synthetic chemicals are continuously used, and their toxicity endangers health farm operators, animals food consumers. The negative effects on human led to a resurgence interest in botanical insecticides due minimal costs ecological side effects. In this, we review use plant compounds (essential oils, flavonoids, alkaloids, glycosides, esters fatty acids) having anti-insect importance as an alternative chemical used elimination insects different ways, namely repellents, feeding deterrents/antifeedants, toxicants, growth retardants, chemosterilants, attractants. Botanical affect only target not destroy beneficial natural enemies provide residue-free safe environment. We, therefore, recommend using integrated insect management program which can greatly reduce insecticides.

The reference condition: predicting benchmarks for ecological and water-quality assessments

Journal of the North American Benthological Society, Год журнала: 2010, Номер 29(1), С. 312 - 343

Опубликована: Март 1, 2010

Benchmarks provide context and are a critical element of all ecological assessments. Over the last 25 y, hundreds papers have been published on various aspects assessments, most analyses described in these depend specifying an benchmark for context. Freshwater scientists managers usually use reference sites (typically natural or least-disturbed condition) to assess conditions at other sites. Accurate precise assessments require that assessed be matched with appropriate conditions. Two general types approaches proposed predict conditions: classifications based environmental settings models continuously variable attributes as inputs. examined: geographic-dependent regionalizations landscape features geographic-independent typologies typically combinations regional channel features. We examined >1000 addressed some aspect predicting condition freshwater ecosystems. focused 5 benchmarks: ecological, thermal, hydrologic, geomorphic, chemical.
