The use of mussels as indicators of pollution in fresh- and seawater was reviewed and the ability of the freshwater mussel 'Anodonta anatina' to absorb Cadmium-115m and zinc-65 from its environment was studied. The uptake was studied when the metals were available in solution only and in the algal food supply. A higher accumulation occurred in the tissues when the metals were available in the food and they were concentrated up to 2x10[sup]3 times for zinc-65 and 1x10[sup]3 times for cadmium-115m above the levels found in the water. Those tissues with large surface areas in contact with the water (i.e. the gills and the mantle) and those involved with processing food (i.e. the digestive gland and kidney) were found to take up the tracers most rapidly. The muscular tissues took up the least amount of tracers. The uptake into the tissues from each source was compared and the metabolic consequences discussed. Depuration of the metals from the tissues was studied when the mussels were placed in uncontaminated water. Although the total body burdens of the tracers declined, a loss was not recorded for all the tissues. For some tissues, notably the digestive gland and the adductor muscles with cadmium-155m and the gonad and kidney with zinc-65, a continued uptake was recorded. It was concluded that permanent binding sites for the metals might exist in some tissues. The fate of cadmium in the tissues was studied. Cadmium was found to be located in the cytosol and associated with low molecular weight proteins. These proteins were found to have low aromatic amino acid and high cysteine content as indicated by their absorption characteristics at 280 and 250 nm respectively. These properties together with the demonstrated heat stability indicated that the cadmium-binding proteins in 'Andonta' are similar to metallothioneins indentified in other species.

Management of organic waste is a major problem for the New Zealand Mussel Industry. Currently most waste is discarded, and this represents a potential loss of both resources and revenue, unless an alternative use for this waste could be developed. Waste types were first identified, then quantified, first seasonally, then annually, to provide an estimate of total industry-wide waste production. Possible uses for this waste were then identified. Little investigative research has been undertaken on identifying alternative uses for mussel industry organic waste. The uses of organic waste as organic fertilizers, and the economic benefit of adding treated waste products to cement mix to improve its compressive strength and thermal insulation, are two primary objectives of this dissertation. The possibility of using mussel shell in agricultural liming as a substitute is also explored. The potential value of pre-grade waste as an organic fertilizer was explored by addition of decomposed tissue to tomato seedlings and by monitoring plant development and condition. Growth of treatment and control seedlings was monitored by counting the number of branches, stem heights, leaf numbers and total biomass. Analyses prove Perna canaliculus pre-grade organic waste has the potential to be exploited as an expensive, effective organic fertilizer, whereas Mytilus galloprovincialis pre-grade organic waste may not. Moreover, there is further potential to develop P. canaliculus pre-grade organic waste into an odourless, chemically stable fertilizer product. The potential value of post-grade waste in cement mixes to improve compressive strength was explored by addition of shell aggregate to cement mix. Analyses indicate that, as an aggregate, mussel shell has little to no structural potential, but does have latent thermal insulating properties. Recommendations are made to: - Separate Perna and Mytilus pre-grade waste products. - Further explore the thermal insulating potential of mussel-shell concrete. - Further explore techniques for treatment of Perna pre-grade waste as a fertilizer. - Further explore the use of crushed mussel shell as a potential limestone or sand substitute for agricultural, construction and engineering purposes. - Explore markets for Mytilus potential export, to reduce pre-grade waste production and problems of resettlement.
