Soil And Water

Chemical, biological, radiological, or nuclear (CBRN) contamination of the environment is a significant threat to human health and life as well as environmental safety. It is then necessary to take actions aimed at minimizing and eliminating the threat. Depending on the type of contamination, various methods are used, including sorption, biodegradation, separation, or ion exchange processes in which membranes play an important role. The type of membrane is selected in respect of both the environment and the type of neutralized pollutants. Therefore, the production and modification of membranes are being adapted to the type of contamination and the purpose of the work. This article presents examples of membranes and their possible applications depending on the part of the environment subject to reclamation and the type of contamination.

Night Sky

One of the least discussed aspects of environmental law is light pollution. Air and water contamination are issues that have been addressed by laws at the federal and state levels but far less attention has been given to the issues of illumination which can have deleterious effects not only on human health but also on the ability to view the night sky. Some states have passed “Dark Skies” laws to remedy these problems.

Brazil is the world’s largest consumer of pesticides and numerous studies have reported damage to both human health and the environment due to exposure and the toxicity of these agrochemicals. Sugarcane crops present the highest herbicide consumption, leaving the margins of large watersheds. In this study, we have investigated the occurrence of herbicides in the surface waters of three different catchment areas, the rivers: Tracunhaém, Três Bocas and Capibaribe Mirim, all located in Goiana, Pernambuco, in a region outstanding for its intense agroindustrial activity, coastal marine biome and areas of shrimp farming. These rivers supply the domestic, industrial and agricultural consumption of around 26 municipalities of the North region of the Zona da Mata in the state of Pernambuco, and has a population of 465,549. Twelve herbicides were investigated in the waters of the Goiana River using the ultra-efficient liquid chromatography technique coupled with triploquadrupole mass spectrometry (UPLC-MS/MS). The study was conducted from March to August 2019 and detected the presence of residues from the herbicides Ametryn, Atrazine, Diuron and Tebuthiuron during March, April and May, in concentrations ranging from 10 to 150 µg L-1. The results indicate the need to monitor surface water contamination, as current agricultural practices have an unprecedented impact on water quality and consequently on ecosystems and human health.

BACKGROUND: Aedes aegypti is one of the most vicious mosquitoes, known for its role in several deadly diseases, including dengue fever and Zika. Several strategies have been developed over decades to prevent vector-borne diseases; one of them is insecticide to control the mosquito population. However, this strategy would not last long due to the elevation of resistance, environmental problem, and some issues regarding human health. Natural products have become major options to combat the glitches. Lemongrass (Cymbopogon citratus) has known for its toxic effect on mosquito larva. AIM: The objective of this study was to assess the effect of C. citratus extract against fourth instar of A. aegypti larvae. METHODS: Three extract concentrations, 2.5%, 5%, and 7.5%, were used. The larvicide activity was evaluated at 2, 4, and 6 h. Our data indicated that all concentrations contributed to increase larvae mortality. RESULTS: Lethal Concentration (LC) 50 and LC90 were achieved at 2.5% and 4.1% of extract, respectively. CONCLUSION: C. citratus  extract has a larvicide activity against fourth instar of A. aegypti.

- The aim of this paper is to investigate people's perception and preference for the remediation and reuse of industrial brownfields sites. Other main objectives are to investigate if people know about abandoned and contaminated sites and if they understand the potential beneficial effects deriving from cleanup and reuse of these sites. Moreover we want to understand if people perceive soil and water contamination and if they consider themselves exposed to environmental risks caused by contaminated sites. Do they support remediation and reuse initiatives? What are their preferred reuse options? Method and Results In order to understand people's opinions we have administered a questionnaire to the residents in the surroundings of Venice. The questionnaire was selfadministered by the respondents using computers and we collected 400 questionnaires. Conclusions We find that people are very familiar with the problem of contaminated and abandoned sites and they are mainly worried about the effects of contamination on human health and on the general environment. Furthermore, they strongly support future public reuse programs like green parks, cultural and other recreational facilities. They don't appreciate industrial and other productive reuse alternatives.JEL: Q53, R52, I18
