Anthropogenic emissions of ammonia cause a host of environmental impacts, including loss of biodiversity, soil acidification and formation of particulate matter in the atmosphere. Under the auspices of the UNECE Convention on Long Range Transboundary Air Pollution, around 80 international experts met to review the state of scientific knowledge. This book reports their analysis. It concludes that threshold levels for ammonia effects have been underestimated and sets new values, it assesses the independent evidence to verify reported reductions in regional ammonia emissions, and it reviews the uncertainties in modelling ammonia, both in "hot spots" and at the regional scale.

Eve has had it--she's no "wicked stepmonster" in the making. She absolutely adores Ian, the new man in her life, and she's more than willing to open her heart to his kids. But nothing she does is right in their eyes, and she just can't take it anymore.

At her wit's end, she decides it's time for stepmothers to stick together, so, with a little prodding from her best friend, Clare, she decides to join a support system for other women in the same boat. There's stay-at-home mom Mandy, high-achiever Mel, and even young and in love Chloe. And as cups of coffee give way to wine, and their get-togethers become a regular fixture, the women share their love, lives, ambitions, and true feelings about their new families.
