Enhanced Removal of Pb(II), Cd(II), and Zn(II) Ions from Aqueous Solutions Using EDTA-Synthesized Activated Carbon Derived from Sawdust

Onyedikachi G. Okpara, Osareme M. Ogbeide, Jeremiah N. Nworu, Jude I. Chukwuekeh, Solomon A. Igoche, Friday S. Alichi, Okechukwu E. Orinya
EDTA synthesized activated carbon derived from sawdust, was utilized as adsorbent for the removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The adsorptive characteristics and elemental composition of this activated carbon were studied using SEM and EDX techniques respectively, the analysis revealed that SAC-EDTA contained 71.95% by weight of carbon contents which are requisites for the high adsorption capacity. The effect of initial metals ions concentration, adsorbent dose, cont...

Teratogenic Investigation of Bay Leaf (Syzygium polyanthum Wight.) Ethanol Extract on Morphology of Fetal Mice (Mus musculus L.) Strain DDY

Marissa Angelina, Aulia Ovy, Indah D. Dewijanti, Ainul Mardhiyah, Luthfiralda Sjahfirdi
This research was conducted to observe the teratogenic potential of S. polyanthum ethanol extract on morphology of fetal mice strain DDY. Thirty pregnant female mice were divided into 5 groups, normal group and treatment groups with dose 0.5; 5; 50; 500 mg/bw. The extract was given orally from 6th to 15th day of gestation. The results showed that the effect of S. polyanthum ethanol extract at a dose of 0.5 mg/bw did not cause resorption and external malformation. At a dose of 5 mg/...

Venomous Stings and Bites in the Tropics (Malaysia): Review (Non-Snake Related)

Xin Y. Er, Iman D. Johan Arief, Rafiq Shajahan, Faiz Johan Arief, Naganathan Pillai
The success in conservation and increase in number of nature reserves resulted in repopulation of wildlife across the country. Whereas areas which are not conserved experience deforestation and destruction of animal’s natural habitat. Both of these scenarios predispose mankind to the encounter of animals, some of which carry toxins and cause significant harm. This review dwells into the envenomation by organisms from the land and sea, excluding snakes which are discussed separately. Rapid recogn...

Venomous Terrestrial Snakes in the Tropics of Malaysia: Review

Iman D. Johan Arief, Xin Y. Er, Rafiq Shajahan, Faiz Johan Arief, Naganathan Pillai
The tropics of Malaysia have plenty to offer when it comes to its biodiversity. In the animal kingdom, snakes play a crucial role and form a large component in the ecosystem, with human envenomation being a fairly common problem. From 1965 to 1971, there were 5203 reported cases of venomous snake bites throughout Malaysia, 18 of which being fatal cases. Symptomatology varies, ranging from mild local symptoms on one end of the spectrum to life threatening systemic manifestation on the other end. ...

Successful Treatment of a Supralethal Dose Paraquat Poisoning and Follow-Up Report

Fahuan Yuan, Feng Chen, Yiqin Wang, Daihong Wang
Serious exposure to paraquat (more than 10 ml 20% paraquat) usually results in death due to progressive pulmonary fibrosis. We report successful treatment of an 83-year-old male who ingested 50 ml 20% paraquat and the follow-up result after 19 months. Our successful treatment might due to early and enough gastric lavage, superhigh dose of steroids and ambroxol, and early and long process of blood purification. At follow-up, the patient’s general condition, laboratory reports, pulmonary function,...

Activities of Lactate Dehydrogenase, Methemoglobin, Carboxyhemoglobin and Sulfhemoglobin Concentrations in the Blood of Albino Rats Exposed to Cashew Seed Fume

Makinwa Tunmise Tope, Ibiyemi David Adedotun, Alabi Toyin Dorcas, Okunade Muda Bode, Oniwon Wisdom Otaru, Adeusi Tomilola Esther
Smoke produced in cashew processing factories during roasting of the seed contains toxic chemicals which have adverse health effects on workers exposed to it. This study investigated the effect of cashew seed fume on lactate dehydrogenase (LDH) activity, methemoglobin (Hi), carboxyhemoglobin (HbCO) and sulfhemoglobin (SHb) in the blood of rats exposed to cashew seed fumes (CSF), via the dynamic exposure system. Eighteen (18) male albino rats were used; they were divided into three groups of six ...

Development of Molecular Marker and Variability Characterization of Aspergillus flavus Isolates of Chilies (Capsicum frutescens L.) through RAPD-PCR and Estimation of Aflatoxin B1 by Indirect Competitive ELISA in India

Virendra Kumar, Ajay Kumar, Shailesh Kumar Kannojia, Rana Pratap Singh
Aflatoxin is the most potent toxic substances, these are the group of closely related mycotoxins produced by fungus i.e. Aspergillus flavus. Twenty seven isolates of A. flavus designated as Af-1, Af-2, Af-4, Af-5, Af-7, Af-9, Af-11, Af-12, Af-13, Af-15, Af-25, Af-28, Af-31, Af-33, Af-34, Af-35, Af-36, Af-37, Af-39, Af-40, Af-46, Af-47, Af-54, Af-55, Af-58, Af-59 and Af-60 were collected from different agro climatic conditions from chilies (Capsicum frutescence) samples. Random amplified polymorp...

Toxic Effect of Imidacloprid on Protein Content in Estuarine Clam, Katelysia opima (Gmelin)

Madhura D. Mukadam, Arvind S. Kulkarni
The indiscriminate use of insecticide has caused serious pollution problems of aquatic ecosystems. Imidacloprid is mainly used to control sucking insects such as rice hoppers, aphids, thrips and some species of beetles. Further it is known to cause apathy, myatonia, tremor and myospasms in humans. Toxic effects of imidacloprid were estimated by selecting Katelysia opima as an animal model. Effect of imidacloprid on total protein content of gill, mantle, hepatopancreas, foot, male gonad an...
