The results of a study on Ligurian women at the third day of puerperium are presented. The data obtained from the analysis of urinary cadmium levels in puerperae are related to their smoking habits and to the newborn weight. We found that women who smoked during pregnancy run the risk of giving birth to small-weight children one-and-a-half times higher than women who didn't smoke; moreover, cadmium levels in the urine of the women who smoked are higher too. The cadmium levels in urine on average are higher in women who gave birth to small-weight children, independently of smoke habits. We didn't find a significant relationship between cadmium levels in urine and newborn weight.

Prenatal metal(loid) exposure and preterm birth: a systematic review of the epidemiologic evidence.
J Expo Sci Environ Epidemiol

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.

Unlabelled: Hazardous heavy metals, particularly cadmium (Cd), are widely distributed in the environment and cause oxidative stress in various animal and human organs. Clove oil (CLO), a common aromatic spice, has been used as a traditional medication as it has potent anti-inflammatory, antioxidant, and hepatoprotective properties.
Background/objectives: This study aimed to investigate the antioxidant, antiapoptotic, and anti-inflammatory effects of clove oil (CLO) against hepatorenal toxicity induced by cadmium (Cd).
Effect of Speciation Transformation of Cadmium (Cd) on P-Wave Velocity Under Moisture Regulation in Soils.

This study aims to investigate the influence of cadmium (Cd) speciation transformation on P-wave velocity under different soil moisture conditions, providing critical insights into the subsurface characteristics of contaminated soils. Taking Cd-contaminated soil as the research subject, P-wave velocity and the speciation distribution of Cd in soils with different moisture contents and Cd adsorption levels were measured. The results reveal that when the soil is contaminated by Cd, the porosity is altered and it eventually lead to change P-wave velocity.

Cadmium (Cd) is a pervasive heavy metal pollutant released into the environment through industrial activities such as mining, smelting, and agricultural runoff. This study aimed to investigate the molecular and metabolic impacts of Cd exposure on the silk glands of , a species renowned for producing silk with exceptional mechanical properties. Cd accumulation in spider bodies and silk glands was significantly higher in the low- and high-Cd groups compared to controls, with a dose- and time-dependent increase.
