Course: Sustainable Development in Health and Ecology

In 2011, a food scandal was reported in Taiwan where diethylhexyl phthalate (DEHP), a plasticizer primarily used for improving the flexibility of PVC products, was found to be adulterated in …

In this video, the professor describes the methodology for calculating the daily intake of DEHP, a type of phthalate, in tainted food. The daily intake was calculated based on various …

The use of biological markers in biomonitoring involves several considerations, such as the best specimen, time of collection, and chemical to measure. Analytical considerations include specimen stability, contamination, and method …

Pharmacokinetics is an important factor in selecting matrices for biomarker analyses. The half-life of a chemical determines how long biomarkers can detect exposures, with longer half-lives reflecting exposures over months …

Biomonitoring results can be interpreted using descriptive or risk-based approaches, or by comparing them to pharmacokinetic modeling. Descriptive approaches involve establishing a reference range and characterizing a chemical’s use pattern …

The estimation of human exposure to potentially harmful chemicals involves calculating the exposure dose, which is expressed in units of milligrams of chemicals per kilogram of body weight per day. …

Biomonitoring is an approach used to measure the trace concentration of chemicals inside the human body. This approach integrates all sources and routes of exposure, including air, dust, food, water, …

The presented figures and information highlight the relationship between environmental and biological monitoring and how policy or regulations can influence biomonitoring results. The figures demonstrate the significant impact of lead …

Insecticide resistance can be evaluated using bioassays. The two commonly used assays are the WHO cone assay and the CDC bottle assay. The WHO cone assay involves attaching standard WHO …

This week, we will discuss exposure assessment-biomonitoring. Professor Chang recommends two textbooks related to the topic and introduces the concept of the human exposure assessment process. He explains the increasing …

To assess human exposure to chemicals, several important exposure parameters must be considered, including the concentration of chemicals in the air or ingested materials, the duration and frequency of exposure, …

Mosquito ecology is an essential aspect of understanding the transmission of mosquito-borne diseases. The female mosquito requires a blood meal for oviposition, but some species, like Culex molestus, can lay …

River and stream ecosystems rely on algae as the primary producer, followed by major invertebrates and fish as primary and secondary consumers. Two major animal groups, fish and macroinvertebrates, are …

The process of biomonitoring for water quality involves two major steps, sampling and laboratory processing. Sampling methods vary depending on the taxa being studied, but electrofishing, surber samplers, and kicking …

In this video, Prof Fan explains the concept of bioindicators and how living organisms can be used to assess the health of natural ecosystems. Bioindicators are biological tools that evaluate …
