Metaldehyde removal from aqueous solution by adsorption and ion exchange mechanisms onto activated carbon and polymeric sorbents.
Metaldehyde removal from aqueous solution was evaluated using granular activated carbon (GAC), a non-functionalised hyper-cross-linked polymer Macronet (MN200) and an ion-exchange resin (S957) with su...Read More
Comparison of UV/H2O2 and UV/TiO2 for the degradation of metaldehyde: Kinetics and the impact of background organics.
The kinetics of photodegradation of the pesticide metaldehyde by UV/H(2)O(2) and UV/TiO(2) in laboratory grade water and a natural surface water were studied. Experiments were carried out in a bench s...Read More
Suspected metaldehyde slug bait poisoning in dogs: a retrospective analysis of cases reported to the Veterinary Poisons Information Service.
A retrospective analysis of telephone enquiries to the Veterinary Poisons Information Service found 772 cases with follow-up concerning suspected metaldehyde slug bait ingestion in dogs between 1985 a...Read More
The dissipation of metaldehyde on cabbage and in soil was studied and half-life (DT(50)) was estimated in a field study carried out at three different locations. Metaldehyde was sprayed on cabbage at ...Read More
Analysis of molluscicide metaldehyde in vegetables by dispersive solid-phase extraction and liquid chromatography-tandem mass spectrometry.
This paper describes the development and validation of a new reverse-phase liquid chromatography-electrospray ionisation tandem mass spectrometric method (RP-HPLC-ESI-MS/MS) for the determination of m...Read More
Identification of environmental factors limiting plant uptake of metaldehyde seed treatments under field conditions.
Slugs are serious pests of oilseed rape (canola) and wheat with most damage occurring just after sowing and seedling emergence. As an alternative to the use of bait pellets, molluscicidal seed treatme...Read More
Determination of metaldehyde in human serum by headspace solid-phase microextraction and gas chromatography-mass spectrometry
A rapid headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) method has been developed for the determination of metaldehyde in human serum samples. Metaldehyde is...Read More
Over a 12-day period, 13 animals in a herd of 110 beef cattle developed ataxia with profound muscle fasciculations progressing to recumbency. Twelve animals (5 adults and 7 calves from 8-10 months of ...Read More
A laboratory-based comparison of a molluscicide and an alternative food source (red clover) as means of reducing slug damage to winter wheat.
Slugs are major pests of many crops in the UK, including winter wheat, yet current methods of control are often unreliable. This study investigates the potential use of red clover, as an alternative f...Read More
To evaluate the molluscicidal effect of wettable powder of 50% niclosamide ethanolamide salt (WPN) and suspension concentrate of 26% metaldehyde and niclosamide (MNSC) on Lymnaea.WPN and MNSC were pre...Read More

Surveillance. SAC C vs disease surveillance report. Cases of poisoning in Scottish cattle and sheep.
Effect of prolonged status epilepticus as a result of intoxication on epileptogenesis in a UK canine population.
The aim of the present study was to investigate if prolonged status epilepticus (SE), secondary to a chemoconvulsant, can induce spontaneous recurrent seizures in dogs. Clinical records at two UK refe...Read More
Molluscicidal activity of cardiac glycosides from Nerium indicum against Pomacea canaliculata and its implications for the mechanisms of toxicity.
Cardiac glycosides from fresh leaves of Nerium indicum were evaluated for its molluscicidal activity against Pomacea canaliculata (golden apple snail: GAS) under laboratory conditions. The results sho...Read More
Backbone cyclised peptides from plants show molluscicidal activity against the rice pest Pomacea canaliculata (golden apple snail).
Golden apple snails ( Pomacea canaliculata) are serious pests of rice in South East Asia. Cyclotides are backbone cyclized peptides produced by plants from Rubiaceae and Violaceae. In this study, we i...Read More
