Environmental advances

Food safety has become an area of primary concern over the past several decades, especially since sociological statistics show a linear association between increased incidence of chronic the level of industrialization, which is associated with environmental pollution, and the scale of industrially processed foods.

The growth of waterborne pathogens and the discharge of partially treated or non-treated chemical waste has become a severe environmental and health risk. Conventional wastewater treatment methods have become less effective, and most current techniques require multiple stages for the disinfection of antimicrobial-resistant (AMR) pathogens and the combined removal of toxic, non-biodegradable, or emerging priority pollutants from wastewater.

In this work, we review various PhCs detected in water treatment plants. We propose that fungi, particularly white-rot fungi (WRF), can be used for their bioremediation and describe the main mechanisms used for degrading this type of emerging pollutants; however, we also highlight the need to prospect for new fungal models.

In the present study, to evaluate a microalga’s responses to a macronutrient’s limitation and the excess to a micronutrient, we acclimated the well-distributed freshwater microalga Ankistrodesmus densus to N- or P-limited medium before exposing it to sublethal copper (Cu) concentrations.

The results indicate a statistically significant increase in extreme rainfall at the expense of light, moderate, and heavy rainfall over time. The only negative relationship is found in dry days. The most statistically significant trends exist in the 99th percentile, maximum, and R100 parameters with p-values of 0.07, 0.08, and 0.11, respectively

The rejects and membrane wash water were also treated in the bioreactor, resulted in complete removal of ClO4 ¯ through this approach. This is the first report where biotreatment is adopted as a pre- and post-treatment to membrane process for removing ClO4 ¯ , and this will find field application for treating ClO4 ¯ contaminated ground as well as surface water sources.

Bayesian kernel machine regression (BKMR) analysis was used to evaluate the univariate contaminant exposure effect as well as the contaminant mixture effects on levels of thyroid hormones. Significant and positive associations were found between total T3 and PC-2 (high positive nickel and cadmium loadings), total T3 and PC-3 (negative association with negative loading for nickel and positive loading for cadmium) and TSH and PC-1 (high positive loadings for organic contaminants).

Water quality indicated by chemical oxygen demand, total nitrogen, ammonium nitrogen, and total phosphorus from the effluent complied with the widely accepted limits on domestic wastewater discharge. Our results demonstrate that green roofs can be designed for the ecological treatment of domestic wastewater on the household scale.

To build trust across many sites (laboratories, regulatory agencies, contract research organizations, chemical producers, and the public), stakeholders will need to agree on validation requirements for particular uses (content in relation to context) as well as how results are to be communicated (data format), and measured (metrics). There is also a need for a global orchestrator, who can exert leadership and inspire voluntary cooperation of diverse organizations to address shared validation goals, to play a key role.

In addition to reduction, MB decolorization mainly results from adsorption on the surface of GdB6 based on the adsorption-desorption tests. The adsorption behavior follows the pseudo-second-order kinetics and Freundlich isotherm model.

The geochemical behavior of Pb in terrestrial and coastal water systems significantly influences Pb biogeochemical cycling and pollutant exchange at the land-sea continuum. An ideal case study of Pb environmental geochemistry is Galveston Bay, an anthropogenic estuary exposed to industrial runoff, wastewater and shipping vessel spills but also fed by natural rivers.

The sedimentary record confirmed that microplastics have been accumulating in these estuaries since the early 1950s, and their abundances have increased greatly in more recent years in response to the progressive urbanization of the watersheds and intensification of land uses. Our results highlight the role of salt marsh sediments as sinks for microplastics in the marine environment.

Pig farming generates highly polluting wastewaters which entail serious environmental issues when not adequately managed. Microalgae systems can be promising for cost, energy and environment-efficient treatment of piggery wastewater (PWW). Aside from clean water, the produced biomass can be used as biostimulants and biopesticides contributing to a more sustainable agriculture.

RTW photodegradation experiments exhibited removal efficiencies of 53.25 % for apparent color, and 64.55 % for turbidity. Phytotoxicity assays using cucumber seeds showed low toxicity of the samples after photodegradation, which indicated that toxic compounds were fully mineralized.

The results showed that SS demonstrated substantially higher impact in total (5.47 Pt) and across each of the endpoint categories, most notably human health (3.12 Pt). Further investigations demonstrated that this was largely fed by the respiratory inorganics midpoint category that accounted for 50 % of the total impact (2.75 Pt).

This paper sets out a workflow that addresses these shortcomings. Tape lifting (a forensic approach to particulate recovery) is at the heart of this workflow. This technique uses self-adhesive tape to recover particles of interest and results in a tape lift in which those particles are held between the tape and a sheet of suitable material.

The ingestion of the fungicide in the larval stage can impair the bee development and the health and performance of the colony. In this perspective, studies that consider the effects of fungicides in the different stages of bee development are crucial for a better interpretation of the risks of exposure.
