Periclase/calcite nanocomposites (PCN) were synthesized via calcination and carbonation treatment of dolomite. The surface and structural properties of PCN were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), N2 adsorption-desorption isotherm, thermogravimetry (TG), and transmission electron microscopy (TEM). The potential of PCN to remove Pb(II) from aqueous solutions was examined by batch experiments.

Solid-phase extraction (SPE) on activated carbon derived from coconut shell (CSAC) for the preconcentration of four varying polarity pesticides (imidacloprid, acetamiprid, simazine, and linuron) prior to their determination using high performance liquid chromatography with diode array detector (HPLC-DAD) was investigated.

A novel approach is presented to determine four bisphenols in water and urine samples, employing magnetic dispersive solid‐phase extraction combined with liquid chromatography and diode array detection. A modified zeolite‐based magnetic composite was used as an efficient sorbent, combining the advantages of magnetic materials with the remarkable properties of zeolites.

Cadmium (Cd) is a heavy metal ion leading to morphological and physiological disorders in plants; a specific toxicity target is the membrane lipids. The total lipids were separated by thin-layer chromatography, and the fatty acid composition of the total (TLs), polar lipids (PLs) and triacylglycerol (TAG)—a neutral lipid—was analyzed in maize seedlings in hydroponics and treated by various Cd concentrations (0–200 µM Cd).

Calcium citrate, chitosan, and chitooligosaccharide were added to sugarcane juice to investigate their effect on color, pH, antioxidant activity, reducing sugar, acrylamide and HMF mitigation in dark brown sugar production. Results showed that the content of 52–67% acrylamide in the dark brown sugar was mitigated with 0.1–1.0% chitosan addition and the reducing power of dark brown sugar increased with 0.5–1.0% chitosan addition.

Polycyclic aromatic hydrocarbons (PAHs) upset the basic biological parameters of the soil, such as enzymatic activity, which can be used to identify the direction and intensity of organic and mineral substance transformation in the soil environment.

ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous soil organic pollutants. Although PAH-degrading bacteria are present in almost all soils, their selection and enrichment have been shown in historically high PAH contaminated soils. We can wonder if the effectiveness of PAH biodegradation and the PAH-degrading bacterial diversity differ among soils.

2,5-Furandicarboxylic acid (FDCA) is attracting increasing attention because of its potential applications as a sustainable substitute to petroleum-derived terephthalic acid for the production of bio-based polymers, such as poly(ethylene 2,5-furandicarboxylate) (PEF). Many catalytic methods have been developed for the synthesis of FDCA, including chemocatalysis, biocatalysis, photocatalysis, and electrocatalysis.

Non-syndromic cleft lip with or without cleft palate (nsCL/P) ranks among the most common human congenital malformations, and has a multifactorial background in which both exogenous and genetic risk factors act in concert. The present report describes a genome-wide association study (GWAS) involving a total of 285 nsCL/P patients and 1212 controls from the Netherlands and Belgium.

In vitro assays presently used for prenatal developmental toxicity (PDT) testing only assess the embryotoxic potential of parent substances and not that of potentially embryotoxic metabolites.

Polar Organic Chemical Integrative Samplers (POCIS) were deployed in two watersheds in Córdoba province and one watershed in Buenos Aires province in Argentina. The fungicides, tebuconazole, carbendazim and azoxystrobin, and the herbicides, atrazine, dicamba and 2,4-D were detected in POCIS deployed in each of the three watersheds.

In the study, we have analysed the impact of lead (Pb), cadmium (Cd), chromium (Cr) and copper (Cu) on fine root biomass and the associated level of bioacumulation heavy metals in fine roots under alder plantings (Alnus incana, A. glutinosa and A. viridis) growing on technosols developed from combustion wastes and extremely poor quaternary sands excavated by sand mining.

The quality of the forecasts, i.e., the accuracy in predicting the observed streamflow, affects the decisions that can be taken thus determining the success or failure of hydropower operations, i.e., the so‐called forecast value.

Consumers’ demand is increasing for safe foods without impairing the phytochemical and sensory quality. In turn, it has increased research interest in the exploration of innovative food processing technologies. Cold plasma technology is getting popularity now days owing to its high efficacy in decontamination of microbes in fruit and fruit based products. As a on‐thermal approach, plasma processing maintains the quality of fruits and minimizes the thermal effects on nutritional properties.

BACKGROUND The consumption of pesticides‐contaminated sour cherry as fruit or juice has become a major health concern, and thus, intensified the search for alternative processing technologies such as pulsed electric fields (PEF), ozone (O), and ultrasonication (US).
