Factors Influencing Color of Dark Cutting Beef Muscle
Color of dark cutting beef rib muscle was measured as affected by treatment with rotenone or chilling in an oxygen rich atmosphere. Samples homogenized with the mitochondrial inhibitor, rotenone, or pH 5.0 buffer remained red for up to 1 hr. Control samples blended with water remained red when chilled but turned dark when held at room temperature. Thin slices of dark cutting beef muscle would turn red when chilled in air or oxygen to 3°C, or when chilled in oxygen to 14°C, but would turn dark when transferred from oxygen at 3°C to air at room temperature. Thus, dark cutting beef muscle will turn red if mitochondrial respiration is inhibited, allowing myoglobin at muscle surfaces to remain oxygenated

Effects of Low Temperature and Increased Oxygen Concentration on Color of Intact Pre-rigor Muscle
Applying the ecosystem service concept to air quality management in the UK: a case study for ammonia
To date evaluation of the benefits of policies to control emissions of air pollutants in the UK has focused on human health effects, which are quantified economically, whereas ecosystem protection has been assessed using critical levels and critical loads. This paper considers the current feasibility of using an ecosystem services approach to appraise the benefits of alternative scenarios for controlling agricultural ammonia emissions in the UK. The effect of ammonia emission reductions on ecosystem service delivery was assessed using an impact pathway approach. A ‘weakest link’ analysis identified that economic valuation of impacts on many key ecosystem services was constrained by inadequate dose–response relationships to predict physical changes in service flows and/or by an inability to produce economic valuations of the predicted physical changes. For effects on biodiversity, both the timescale of response and poorly defined relationships between changes in species composition and ecosystem service delivery are significant barriers. However, it was possible to produce indicative values for the marginal impact of ammonia abatement measures on climate regulation; the values obtained were comparable in magnitude to those for human health impacts. The ecosystem service approach thus offers the potential to provide a holistic appraisal of the effects of emission reductions, and could therefore make a valuable contribution to future air quality management. However, improvements in data collection and quantification methods are needed before a full ecosystem services-based evaluation of costs and benefits becomes possible for ammonia and for other major air pollutants
