State Key Laboratory of Clean Energy Utilization, Institute for Thermal Power Engineering, Zhejiang University, China. Electronic address:
Article Synopsis
- The steel industry is a major source of dioxins (PCDD and PCDF), mainly produced during processes like sintering and hot rolling, and there’s concern about their emissions from burning hot rolling sludge (HRS).
- Incinerating HRS with spent anion exchange resin (SAER) showed significant reductions in dioxin emissions, achieving up to 97.8% reduction with higher resin amounts.
- Further studies are needed to fully understand the effect of SAER on dioxin formation and to analyze the increased sulfur levels in the off-gas and combustion residues during co-combustion.

Ifremer, Laboratoire Phycotoxines, Rue de l'Ile d'Yeu, 44311 Nantes, France.
Article Synopsis
- Algal toxins that accumulate in seafood can cause poisoning in consumers, but not much research has been conducted in Africa, particularly regarding Nigeria's coastal waters.
- A survey conducted in Nigerian coastal areas identified various phytoplankton species dominated by diatoms, cyanobacteria, and some dinoflagellates while also analyzing for algal toxins using passive samplers.
- Quantifiable levels of okadaic acid (OA) and pectenotoxin 2 (PTX2) were detected, with varying concentrations noted at different sites, suggesting the presence of harmful algal blooms despite less than ideal environmental conditions.

Biochemistry Programme, School of Life Sciences, The Chinese Univ. of Hong Kong, Shatin, N.T., Hong Kong.
Article Synopsis
- Chlorogenic acid (CA) is an important compound found in various foods and herbal remedies, and boiling can transform it into two isomers (4-O-CA and 5-O-CA).
- A new purification method was developed, achieving high yields and purity for CA and its isomers: 82% for CA, with purities of 98%, 97%, and 99% for CA, 4-O-CA, and 5-O-CA, respectively.
- The study found that while all three compounds have similar antioxidant activity, boiling does not reduce CA's effectiveness, and the main change is the formation of its isomers.

March 2009
Department of Clinical Medicine, Faculty of Medicine, University of Colombo, Colombo 8, Sri Lanka.
Article Synopsis
- - Poisoning from yellow oleander seeds, which contain toxic cardiac glycosides, is a significant health issue in South Asia, especially among young individuals without prior health conditions.
- - Management involves risk assessment, continuous ECG monitoring for at least 24 hours, and supportive care such as hydration, controlling vomiting, and correcting electrolyte imbalances, particularly potassium and magnesium.
- - Unlike digoxin toxicity, yellow oleander poisoning's effects on serum magnesium are less understood, and gastric decontamination methods like vomiting or lavage lack thorough investigation despite being commonly used.

U.S. Geological Survey, 3215 Marine Street, Boulder, CO 80303, USA.
Article Synopsis
- Researchers studied the effects of wastewater treatment plant (WWTP) effluent on male fathead minnows to assess potential endocrine disruption, particularly focusing on reproductive competence.
- Two experiments were conducted in August and October 2002, revealing that exposure to untreated effluent increased vitellogenin levels more significantly in October due to higher concentrations of harmful compounds.
- Treatment with XAD8 resin effectively reduced vitellogenin induction in the October experiment, demonstrating its potential to mitigate the adverse impact of endocrine disrupting compounds in wastewater.

January 2006
Department of Pharmacology, Faculty of Veterinary Medicine, Alexandria Univerity Research Development, Alexandria, Egypt.
Article Synopsis
- A study investigated the effects of a diet containing lead acetate on oxidative stress and genetic damage in mice, focusing on the role of powdered turmeric and myrrh as protective agents.
- Results showed that lead acetate significantly decreased levels of glutathione (GSH) and the activity of the enzyme glutathione S-transferase (GST), while increasing lipid peroxidation and chromosomal abnormalities in positive control mice.
- Co-treatment with turmeric and myrrh improved GST activity and reduced lipid peroxidation and genotoxic effects, with the most effective results observed with 5% turmeric powder.

School of Studies in Zoology, Jiwaji University, Gwalior (MP), India.
Article Synopsis
- Propolis, a natural substance produced by bees, has historically been used for its medicinal benefits and is being researched for its protective effects on the liver.
- The study examined the effects of different doses of ethanolic propolis extract on liver damage induced by carbon tetrachloride in rats, which led to various harmful changes in biochemical markers related to liver and kidney function.
- Results indicated that propolis extract at doses of 200 and 400 mg/kg effectively restored the disturbed biochemical markers and suggested that its protective effects may stem from its antioxidant properties.

Onderstepoort J Vet Res
June 1995
Division of Toxicology, Onderstepoort Veterinary Institute, South Africa.
Article Synopsis
- Gousiekte, a disease in sheep and goats, was triggered by giving them methanolic and ethanolic extracts from Pavetta harborii through oral and intravenous methods.
- * Further purification of the toxic substance included methods like dialysis and ion-exchange chromatography, leading to the extraction of the toxin with ammonium acetate.
- * The pure toxin, approximately 10 mg/kg from dried leaves, was confirmed to cause Gousiekte in goats when administered intravenously.
Article Synopsis
- * Results showed that the combination significantly increased the excretion of these harmful chemicals, with statistical significance (p < 0.05) noted for both PCB and specific forms of PCDF.
- * The effectiveness of the treatment varied considerably among patients, with excretion rates ranging from 60% to 160% for pentachlorodibenzofuran, 30% to 110% for hexachlorodibenzofuran

Arch Environ Health
November 1994
Department of Hygiene and Epidemiology, University of Udine, Italy.
Article Synopsis
- The study assessed the connection between central nervous system neoplasms (CNSN) and epichlorohydrin (ECH) exposure among 11 affected individuals and 44 control workers in a chemical plant.
- Results showed a significantly increased odds ratio (OR) for CNSN among workers in epoxy resin production and anthraquinone dye manufacturing, indicating potential severe risks associated with these roles.
- A dose-response relationship was identified, suggesting both the duration and intensity of ECH exposure could influence the likelihood of developing CNSN, with acute exposure leading to higher odds of illness requiring medical treatment.
