The alga contains salt and heavy metals that are accumulated in algae poses a significant challenge to the safe use of algae in soil fertilization and other applications. This study examines the relevance of algal biomass as an environmentally friendly fertilizer, thereby contributing to sustainable coastal management practices. In this study, the hot and cold extraction method were done to obtain the Ulva rigida extract.

Contamination of aquatic ecosystems with heavy metals poses a significant global issue due to its hazardous effects and persistent accumulation in living organisms. This study analyzed 51 fish samples from two species of Black Fish, Capoeta saadii and Capoeta trutta, collected from Iran's Khorramroud River during the summer and fall of 2022 to assess heavy metal accumulation in their gill, liver, and muscle tissues. After biometry, the studied tissues of each fish were isolated to measure the concentration of heavy metals (cadmium (Cd), zinc (Zn), chromium (Cr), lead (Pb), copper (Cu), and nickel (Ni)).

Aim: To study the peculiarities of the ratio of the level of leptin and a number of toxic and essential chemical trace elements in biological environments in adolescent boys aged 13-14 years with obesity and delayed sexual development.
Materials And Methods: Three groups of adolescents aged 13-14 years were studied and formed: the main ones - with constitutional exogenous obesity of 1-2 degrees (1-20 boys without secondary signs of puberty; 2 - 24 boys with 2-4 stages of puberty according to Tanner) and comparisons (3 - 15 boys with normal body weight and without deviations in puberty).

This study aimed to compare thirteen different varieties of hyacinth beans analyzedfor their nutritional and antinutritional constituents. The study classified HA-3, HA-4, and Kadale Avare as Lignosus varieties, while the remaining varieties Arka, Pusa, CO, and NS, were classified as Typicus. The protein content ranged from 19.

Background: Preterm birth (PTB) is a common pregnancy complication associated with significant neonatal morbidity. Prenatal exposure to environmental chemicals, including toxic and/or essential metal(loid)s, may contribute to PTB risk.
Objective: We aimed to summarize the epidemiologic evidence of the associations among levels of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), lead (Pb), and zinc (Zn) assessed during the prenatal period and PTB or gestational age at delivery; to assess the quality of the literature and strength of evidence for an effect for each metal; and to provide recommendations for future research.
