今年5月25日浙江省工商局公布了一份儿童食品质量抽检报告，其中雀巢金牌成长3+奶粉中碘含量为191微克（μg）到198微克，要求下架回收．这不禁使人们联想起2004年春发生在安徽阜阳市的震惊全国的“劣质奶粉事件”：几百名婴儿因食用劣质奶粉成为“大头娃娃”，有的甚至死亡．经国务院调查组调查表明，劣质奶粉蛋白质含量为1%．

优质的婴儿奶粉成分（每100克含量）如下表：

蛋白质	亚油酸	脂肪	乳糖	水分	矿物质	维生素	碘
≥18.0g	≥1.6g	≥17.5g	K 58.0g	K5.0g	≤6.5g	≈1.0g	30μg～150μg

请你根据给出的材料分析回答：

（1）这两件奶粉事件都是关于______质量问题．
