Objective: To study the perinatal outcomes of children born from different conception methods: in vitro fertilization (IVF) with autologous oocytes or IVF with donor egg vs. those conceived without medical assistance by using a sibling analysis.
Design: Retrospective cohort study conducted using electronic medical record data from 2000 through 2018, of a national healthcare organization.
The dataset represents micro computed tomography (µCT) images of undisturbed samples of constructed Technosol, obtained by sampling from the top layer of the biofilter in two bioretention cells. A bioretention cell is a stormwater management system designed to collect and temporarily retain stormwater runoff and treat it by filtering it through a soil media called a biofilter. Soil samples were collected at 7, 12, 18, 23, and 31 months after the establishment of bioretention cells.

Cherry tomato () and cabbage ( L.) were irrigated with tap water (Tap), secondary effluent (SE), and membrane effluent (ME).

- A pot experiment assessed how multi-contamination with cadmium (Cd), lead (Pb), and zinc (Zn) affected carrot plants after 98 days of growth in a greenhouse.
- Multi-contamination led to greater accumulation of Cd, Zn, and Pb in the leaves than in the roots, with visible physiological and metabolic changes noted, such as increased malondialdehyde levels and decreased carotenoid content.
- Overall, significant decreases in biomass, alterations in gas-exchange parameters, and changes in enzymatic activities were observed, indicating that carrot leaves were more sensitive to contamination than the roots.
Several studies have shown that plants can absorb various micropollutants. The behavior of micropollutants from wastewater treatment plant resources was comprehensively investigated in raised beds in which either a mixture of vegetables or maize was grown. The beds were either irrigated with treated wastewater or enriched with sewage sludge or composted sewage sludge.
