Examining the relationship between language development, executive function, and screen time: A systematic review.

This systematic review study examines the relationship between language development, executive function, and screen time in early childhood. The early childhood period is a crucial phase for the development of the brain, during which fundamental language and executive function skills undergo rapid evolution. This review synthesizes findings from 14 peer-reviewed studies that focused on language development, executive function, and screen time together to provide a comprehensive understanding of their relationship.

Does eating fish cause cancer? A case study metal(loid)s accumulation in mackerel and sardine tissues from İskenderun Bay, Türkiye.

Due to the increasing harmful effects of metal(loid)s over time, it has become important in environmental studies carried out to increase environmental awareness. It is important to investigate the cumulative presence of metal(loid)s in nature, their interactions with each other and risks posed by fish consumption for human health. Total concentrations of As, Cd, Cu, Fe, Mn, Ni, Pb, and Zn were determined in muscle and gill tissues of horse mackerel (Trachurus trachurus) and sardine (Sardina pilchardus).

Size-selective microplastic uptake by freshwater organisms: Fish, mussel, and zooplankton.

Microplastics, as an emergent pollutant, have garnered substantial attention within aquatic environments, yet a significant knowledge gap persists regarding the interplay of organism size and pollution impacts on microplastic uptake in freshwater ecosystems. The main aim of the current study is to assess the microplastic ingestion by aquatic organisms across diverse trophic levels. To achieve this objective, zooplankton, mussels (Anodonta anatina), and fish (Carassius gibelio) were collected from the highly polluted Susurluk River Basin in Türkiye.

Molecular diversity of some species belonging to the genus Daphnia O. F. Müller, 1785 (Crustacea: Cladocera) in Turkey.

Daphnia is a freshwater zooplankton species with controversial taxonomy due to its high morphological variation linked to environmental factors and inter-specific hybridization and polyploidy in some groups. The aim of the present study is to examine molecular diversity of some Daphnia species in Turkey and to establish DNA barcodes of Turkish Daphnia species. Sequence analysis was performed using 540 bp region of cytochrome oxidase subunit I gene of mitochondrial DNA.

Correlations in metal release profiles following sorption by Lemna minor.

Following the rapid uptake of contaminants in the first few hours of exposure, plants typically attempt to cope with the toxic burden by releasing part of the sorbed material back into the environment. The present study investigates the general trends in the release profiles of different metal(loid)s in the aquatic macrophyte Lemna minor and details the correlations that exist between the release of metal(loid) species. Water samples with distinct contamination profiles were taken from Nilüfer River (Bursa, Turkey), Yeniçağa Lake (Bolu, Turkey), and Beyşehir Lake (Konya, Turkey) and used for release studies; 36 samples were tested in total.

Phytoremediation of Cu, Cr and Pb mixtures by Lemna minor.

The present study reports the capacity of the aquatic macrophyte Lemna minor to remediate combinations of Cu(II), Pb(II) and Cr(III) from a simulated natural environment. The effect of these metal mixtures on the growth of L. minor was also investigated using growth rate and biomass inhibition calculations.

Decrease and increase profile of Cu, Cr and Pb during stable phase of removal by duckweed (Lemna minor L.).

The present work details the decrease-increase profiles of Cu, Cr, and Pb by the aquatic plant Lemna minor. A mixture of these metals were utilized at different concentrations. Removal profiles of each metal was determined with water samples taken every 24 h for a 144 h period after the 48 h mark and was examined with correlation analysis.

Concentration of heavy metals in the food web of Lake Egirdir, Turkey.

The concentration of heavy metals (Cr, Cd, Hg and Pb,) was determined by atomic absorption spectrophotometry in sediment, water, plankton and fish samples from Lake Egirdir in South-Western Turkey. Lake Egirdir is an important bird nesting and visiting areas, and it is also used as irrigation and drinking water source. The heavy metal concentrations were in the order Cd > Pb > Cr > Hg in water, Cr > Pb > Cd > Hg in sediment, Pb > Cd > Cr > Hg in plankton, Cd > Cr > Pb > Hg in the muscle and Cd > Pb > Cr > Hg in the gills of Ctenophatyngodon idella.

Assessment of heavy metal concentrations in the food web of lake Beyşehir, Turkey.

The accumulation of heavy metals (Cd, Pb, Hg and Cr) was measured by atomic absorption spectrophotometry in water, sediment, plankton and fish samples collected from Lake Beyşehir, which is important bird nesting and visiting areas, and irrigation and drinking water sources. In Lake Beyşehir, the accumulation orders of heavy metals were Cd>Pb>Cr>Hg in water, Pb>Cd>Cr>Hg in sediment, Pb>Cd>Cr>Hg in plankton, and Cd>Pb>Cr>Hg in the muscles and gills of chub, carp, tench, except for the muscle of pikeperch, in which it was Pb>Cd>Cr>Hg (P<0.05).
