Article Abstract
Coastal development activities can cause local increases in turbidity and sedimentation. This study characterises the spatial and temporal variability of turbidity near an inshore fringing coral reef in the central Great Barrier Reef, under a wide range of natural conditions. Based on the observed natural variability, we outline a risk management scheme to minimise the impact of construction-related turbidity increases. Comparison of control and impact sites proved unusable for real-time management of turbidity risks. Instead, we suggest using one standard deviation from ambient conditions as a possible conservative upper limit of an acceptable projected increase in turbidity. In addition, the use of regional weather forecast as a proxy for natural turbidity is assessed. This approach is simple and cheap but also has limitations in very rough conditions, when an anthropogenic turbidity increase could prove fatal to corals that are already stressed under natural conditions.

For purpose of overcoming the negative impact of high-dose phenols on meat quality, xanthan gum (XG), a natural anionic polysaccharide, was employed to prevent the undesirable interaction between myofibrillar protein (MP) and gallic acid (GA, 150 μmol/g) and ameliorate the gel and emulsification characteristics of MP. XG dose-dependently alleviated the structural damage of MP caused by GA and reduced protein aggregation, manifested as the decrease in surface hydrophobicity, turbidity and aggregate size (p < 0.05) and increase in α-helix content and intrinsic fluorescence.

In recent years, interactions between polysaccharides and proteins have been widely considered for use to improve protein gel performances. We previously found carboxymethyl chitosan (CMCS) can increase Pleurotus eryngii protein (PEP) gel properties, but the contributions of different key PEP fractions to overall gel formation remain unclear. The aim of this study was to investigate how CMCS affects the gel properties of PEP via intermolecular interactions with PEP fractions, including PEP1-1, PEP2-2, and PEP5-1.

Nitrogen pollution has long been a major threat to river and estuarine ecosystems around the world. However, at present, most of the research focuses on rivers and attached freshwater lakes, and the research on the nitrogen evolution characteristics and driving mechanisms of estuarine alluvial islands at river estuaries remains poorly understood. In this study, four cross-sections in Chongming District from 2021 to 2023, including Qixiaogang West Bridge, Qianweicun Bridge, Wuxiao, and Sanshahong Intersection were Sampled.

In many parts of the world, shallow well drinking water is contaminated and often consumed without treatment, contributing to over 3.4 million deaths annually due to water-related diseases. This research aims to assess the efficacy of Waltheria indica plant root extracts as an affordable method for disinfecting shallow well water in rural Tanzania.
