COVID-19-related lockdowns and changes in overweight and obesity, movement behaviours, diet quality, and health-related quality of life among regional Australian primary school children: A repeat cross-sectional study.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Australian state of Victoria (in particular, its capital, Melbourne) experienced some of the longest lockdowns in the world.

Objective: This repeated cross-sectional study examined changes between March to June 2019 (pre-pandemic) and April to August 2022 (6 to 11 months following pandemic-related lockdowns) in overweight and obesity prevalence, physical activity, sedentary behaviour, sleep, diet quality, and health-related quality of life (HRQoL) among primary school children in north-east Victoria, Australia.

Methods: Height and weight were measured for Grade 2, 4, and 6 students in 2019 (3889 children) and 2022 (1816 children).

The Uptake of Rare Trace Elements by Perennial Ryegrass ( L.).

Technological development has increased the use of chemical elements that have hitherto received scant scientific attention as environmental contaminants. Successful management of these rare trace elements (RTEs) requires elucidation of their mobility in the soil-plant system. We aimed to determine the capacity of (a common pasture species) to tolerate and accumulate the RTEs Be, Ga, In, La, Ce, Nd, and Gd in a fluvial recent soil.

Environmental Parameters Affecting the Concentration of Iodine in New Zealand Pasture.

Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I concentrations. We aimed to identify the most important environmental factors affecting the concentration of I in New Zealand pastures, and the consequences to agricultural systems.

The mobility and plant uptake of gallium and indium, two emerging contaminants associated with electronic waste and other sources.

Gallium (Ga) and indium (In) are increasingly susceptible to soil contamination via disposal of electronic equipment. Chemically similar to aluminium (Al), these elements may be mobile and bioavailable under acidic conditions. We sought to determine extent and nature of Ga and In mobility in the soil - plant system and thus their potential to enter the food chain.
